When Xiao Wu returned to the lounge, he was startled when he heard the movement of the bunk on the opposite side.

Then he saw an elbow in light blue underwear peeking through the gap in the curtain, oh, it was Mr. Fang.

I wonder how Mr. Fang came back to sleep.

didn't think too much about it, closed the curtain and put on headphones, and Xiao Wu also fell asleep.

The alarm clock rang, Xiao Wu rolled on the bed and got up, and was startled by the sound of turning over on the opposite side. Quickly turn off the alarm, yes, Mr. Fang is staying, don't make any noise to her.

However, Xiao Wu watched a day's movie that day, and after exercising - taking a bath - pressing the rub - he finally found a chance to cool down, and came back to see that Mr. Fang was still lying on the top bunk. The curtain is closed.

He couldn't help but be a little worried, Mr. Fang couldn't be sick, right? So he poked his finger at the exposed sleeve of his shirt:

"Mr. Fang? Mr. Fang? ”

"Hmmm......"

Fang Wenjing's weak voice came.

"Did you eat today?"

"Hmm."

"Eaten?? When was it eaten. ”

"Ugh." There was the sound of turning over. Then it's a day and a night without eating.

"Are you feeling unwell, Mr. Fang?"

"Hmm."

"What's uncomfortable, I'll get you medicine?"

"There's a box of my stuff in the storage room with my medicine in it."

"Okay. Wait! ”

After a while, Xiao Wu came back,

"Am I up?"

"Well, set gravity a little higher."

"How tall?"

“1g”

"Okay."

Xiao Wu adjusted the gravity, climbed the bed ladder, and lifted the curtain. saw Fang Wenjing's face sallow, his lips bloodless, and his hair in a mess. A little surprised.

"Wow, you look so haggard!" After that, he hurriedly put the two boxes of medicine and a tube of water in his hand in front of Fang Wenjing.

Fang Wenjing smiled: "It's okay, it'll be fine in two days." "Take the medicine and drink the water. Hand the garbage to Xiao Wu.

Every time she had a depressive episode, her energy would be so low that she couldn't get out of bed for a few days.

"Watching a movie, Mr. Fang? I found a very good film! Hey! ”

Fang Wenjing smiled: "Okay, what kind of film?" ”

"Uh...... I forgot that I went get Xiaoliu's computer for you. ”

Xiao Wu ran down and took a board from downstairs and put it on Fang Wenjing's bed, put the laptop on it, and plugged it in. He used his own pillow to help her raise her head.

It's nice to have someone around.

Fang Wenjing looked at "World War Z" and thought. I didn't see it for ten minutes and fell asleep again.

Xiao Wu was very anxious, he was afraid that Fang Wenjing would die.

I'm even more afraid that she will wet the bed.

After a while, he woke up Fang Wenjing again.

"Mr. Fang, how about I carry you to the weapons room for a massage?"

"Why?"

"Maybe you'll be able to get a massage? Wash a hot water date again and take it for a while? ”

Sounds pretty good.

"Okay," Fang Wen agreed. Climb onto the back of Little Five. Xiao Wu's back is really uncomfortable...... It's too hard, it's not good, and if I'm going to change the guard gene, I'm going to enhance the fat content on my back.

At first, she felt sad again. I feel like I can't do anything but fantasize.

Fortunately, Xiao Wu immediately interrupted her:

"Is this the right temperature?"

"Well, that's good."

Xiao Wu closed the door for her. She sat on her knees under the hot water, letting the hot water wash away.

When Xiao Wu brought Mr. Fang's change of clothes, he found that there was no movement inside. He leaned on the door and listened for another five minutes, but there was no movement inside.

Xiao Wuke panicked again, and hurriedly knocked on the door: "Mr. Fang! Mr. Fang? Are you still there? ”

Hehe, Fang Wenjing smiled: "Yes." ”

"Oh, I brought you a change of clothes, and you opened the door."

Fang Wenjing opened the door and took dry clothes, only to find that Xiao Wu had not taken off her clothes and was drenched.

It's over, it's over, it's over, Fang can't be insane!

Fang Wenjing dried her head, changed her clothes, and felt much better. When he went out, he patted Xiao Wu's shoulder in a daze:

"Thank you, help me get some more rabbit rice."

"Yes!" Xiao Wu went with a sigh of relief.

She returned to the main control room, opened the iron curtain of the shirlwind, took a deep breath and turned on the computer.

I'm going to hold on, even if there's no progress. There is hope if you hold on.

I opened the e-book that Professor Zhao gave her and read it. I don't want to do anything, just read books, study, start with the most basic proteins, enzymes, cells, and chromosomes.

After a while, Xiao Wu came over and took away the leftovers, saw that she was reading, and left without saying anything.

From this day on, her logbook became a scholar:

Day 15: Read the book today, nothing happens, there are still 51.84 million kilometers from the destination, and it is expected that there will be 115 Earth days before reaching the destination.

Day 16: Reading today, nothing happened, there are still 51.46 million kilometers to the destination, and it is expected that there will be 114 Earth days before arriving at the destination.

Day 17: Read a book today, nothing happened, there are still 51.08 million kilometers to the destination, and it is expected that there will be 113 Earth days before arriving at the destination.

Learned a lot.

It turns out that the human age counter is on the telomeres of the cells.

Telomeres are specialized structures at the ends of eukaryotic cells' chromosomes. Human telomeres are composed of a 6-base repeat (TTAGGG) and binding proteins. Telomeres are the "mistosis clock" of normal cells, and the length and stability of telomeres determine the cell lifespan and are closely related to cell aging and carcinogenesis.

At birth, telomeres are the longest, and with each division, the telomeres decrease a little until the telomeres are too short to divide.

This puts an end to cracking. This design, she looked up from the sea of books, there was something.

I thought it was a code with a similar upper limit that could be directly modified, but the telomere length of each cell, this birth, limited what I could do.

That's right, cancer cells.

Cancer cells can divide indefinitely.

Find information about cancer cells directly in all the materials.

"Numerous studies have shown that the immortality of tumor cells is closely related to telomerase activity.

Telomerase plays an important role in maintaining telomere stability, genome integrity, long-term cell activity, and potential ability to continue proliferating.

In normal human cells, the activity of telomerase is very tightly regulated, and only in hematopoietic cells, stem cells, and germ cells, which must constantly divide, can the active telomerase be detected. When cells are differentiated and matured, they must be responsible for the needs of various tissues in the body, so the activity of telomerase will gradually disappear. ”

"Telomerase is an enzyme composed of catalytic proteins and RNA templates that synthesize DNA at the ends of chromosomes, imparting immortality to cell replication."

So, if you can find the protein expression of telomerase, wouldn't you be immortal?

"The activity of telomerase in normal human benign lesion cells is not detectable in fibroblasts cultured in vitro. However, it is positive in germ cells**, ovary, placenta, and fetal cells.

It is a remarkable finding that malignant tumor cells have highly active telomerase, and telomerase-positive tumors include ovarian cancer, lymphoma, acute leukemia, breast cancer, colon cancer, lung cancer, and so on. High telomerase activity is widely present in human tumors. ”

In other words, this enzyme must be present, but not too much, because too many normal cells may become cancerous.

The difficulty, then, is to have an appropriate benign content range.

Yes! Pregnant! The zygote has this enzyme in it! But not in normal cells! I brought a fertilized egg!

Then I changed my mind: No, I only have software to analyze DNA sequences, and I don't have the equipment and materials to detect proteins.

Alas......

Am I overthinking? How can I get the protein structure that so many scientists on the earth can't analyze?

Well, she remembered the definition of genes.

"An individual receives from their parents a myriad of protein formulas they need to grow."

If the essence of genes is the formula, the proteins in the cells must also be in this formula.

Can I, bypassing the chemistry I don't understand, and just crack the code, and find the expression for telomerase?

She thought as she tapped her fingers on the table.

Theoretically, it should be possible.

She copied the expression of the new tooth-boosting gene CTIP2 and searched it in her DNA. The dormant gene segment was found in the gray unknown gene.

(Author's note: In the actual gene expression, each information code will be repeated dozens of times, and the cell will be copied every time it divides.

The meaning of this gene must be "when and when to hibernate the gene?" That is, "when and when to stop the development of new teeth"

Xiao Wu's gene is in an expression state, probably because he is still growing wisdom teeth, right? He started growing up at the age of 19 and is now only 20 years old.

I got my wisdom teeth at the age of 22. So this code snippet, in my body is "22-year-old dormant gene", in Xiao Wu is "20-year-old dormant gene"? Let's say his four teeth are two years long...

Fang Wenjing hurriedly copied the genetic expression of the two of them into a text file. There are only two letters that differ from each other's genes:

Fang Wenjing is: GGHACCCGAAAGGTCTCCTTGCAGGHG

The primary five are: GGHACCCGAAAGGTCTCCTTGCAGGAG

So HG might represent 22 and AG might represent 20?

Okay, that's the first equation I know.

So does the previous meaning mean "abort, hibernation"?

I immediately looked at the three dormant cancer genes on my body, and sure enough, they all had the words GGHACCCGAAAGGTCTCCTTGCAGGXG. It's just different from the prefix of the new tooth-boosting gene. It's the beginning of CCG.

Okay, so what this paragraph means is "dormant", so... What field is "Start"?

Xiao Wu brought her rabbit rice at this time, and she thanked her and devoured it. Once the mood is restored, so is the appetite.
